After the replacement of the /* fall through */ comment with the
fallthrough pseudo-keyword macro, the natural reading of a code
comment was broken.

Fix the natural reading of such a comment and make it intelligible.

Excellent, thanks for the quick turnaround!

And just to be explicit, this fix is for 5.9.

Acked-by: Peter Rosin <peda@axentia.se>

Cheers,

Fine by me, Jonathan might think differently but I can't find a reason why.
Just about nothing is happening in that file and the risk for conflicts is
negligible.

If you don't mind I can add this to my tree for 5.9-rc4
and send it directly to Linus.

Thanks

OK. In the meantime, I have added this to my -next tree and queued it up
for 5.9-rc3.
